Apple fields the best available touch panels in its iPod touch and iPhone, a third-party report indicates.

Apple's move to introduce touch-sensitive devices has spurred competing companies to speak to touch panel manufacturers, and is driving others to consider launching touch panel manufacturing facilities.

A DigiTimes reports that the technological challenge in creating such screens is quite high and failure rates (in which the glass adheres to the touch sensitive surface) quite high.

However incumbents in the space indicate the adhesion rate for top quality devices, such as Apples, has reached 90 per cent.

"The yield rate for Apple's touch panel products will reach more than 90 per cent in 2008, the makers noted, while adding that the yield rate for non-Apple product's will reach 90% during the period," DigiTimes informs.
